Annealed black wire is a kind of soft wire product made of low carbon steel by cold drawing, heating, constant temperature and heat preservation. The components of the wire are different according to their use: iron, cobalt, nickel, copper, carbon, zinc, and other elements. The hot metal billet is rolled into 6.5mm thick steel bars, also known as coils, and then put into the wire drawing device to draw into different diameter lines. And gradually reduce the diameter of the wire drawing plate, cooling, annealing, coating and other processing technology into a variety of different specifications of the wire. Wire production because of simple technology, wide application, earlier development. Wire or steel wire (the corresponding enterprise for the “silk mesh enterprise”) is a cold processing products of steel wire rod again, the materials used generally choose high quality low carbon steel or stainless steel.
Usually annealing black wire process through the plate shell, pickling, washing, saponification, drying, drawing, annealing, cooling, pickling, washing, galvanized line, packaging and other procedures, in order to produce the production of iron wire (steel wire) iron ingot (steel ingot). Black iron wire has good elasticity and flexibility, can control its hard and soft degree in the annealing process, is made of high quality iron wire, mainly used in the construction industry as binding wire and wire.
Annealed black wire commonly used specifications are 5#-38# (wire 0.17-4.5mm) is softer than ordinary black wire, stronger flexibility, softness uniformity, color consistency. Wire and steel wire production generally used drawing technology and galvanized treatment. The drawing process is changed from discontinuous production to continuous production, which weakens labor intensity and reduces metal consumption. In the 1980s, staplings with hot plated low carbon steel wire, fan mesh cover steel wire, carbon structure steel wire, bed steel wire and so on have also come out.
